The Key of Solomon 34688

A cleverly encrypted message left by an astronomy professor for his daughter before his assassination, guiding her to a person going through strange circumstances, forcing them to cooperate to uncover the mystery of people who do not exist and completely illogical suicide cases. Together, they become embroiled in a terrifying archaeological journey through tombs and buildings from the Fatimid era in Egypt, encrypted by the ancients in a sequential and interconnected manner. Through the paths of secrets, they face horrifying horrors, but it was only at the very end, in a place well-known, that we learned the most surprising truths. Oh, if only we hadn't known.
